Upgrading to the current Hobie 18 system would resolve all those problems. I had a Hobie 18 with that old style and it cost me a rudder blade when I couldn't get the cam to pop loose just before entering the surf....mind you, I installed the rudders backwards (port on starboard, etc) so the rudders were highly loaded making the cams stick even harder - that's why I was going back to the beach!
